WEEDER ATTACHMENT FOR CULTIVATQRS.

Application filedMarch is, 1914.

To all whom it may concern Be it known that I, lVEsLEY W. BUNon, acitizen of the United States, residing at Ashton, in the countyoftfipink, Stateof South Dakota, have invented certain new and usefulImprovements in Weeder At tachments for Cultivators; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in cultivator attachments, andparticularly to weeding attachments for cultivator-s.

The principal object of the invention is to provide a simple and noveldevice of this character which can be quickly and easily attached to ordetached from the ordinary straddle row cultivator.

Another object is to provide a Weeding attachment for a straddle rowcultivator which will be eflicient in use and which can be quickly andeasily moved into and out of operation from the drivers seat.

Other objects and advantages will be apparent from the followingdescription, when taken in connection with the accompanying drawings.

In the drawings: Figure l is a top plan view of a portion of acultivator, showing my invention applied thereto and in operativeposition. Fig. 2 is a side elevation of the same. Fig. 3 is a frontelevation. Fig.

el is a longitudinal sectional view showing the connection of the springrod 17 with the bar 23. Fig. 5 is an enlarged fragmentary longitudinalsectional view on the line 5-5 of Fig. 1. Fig. (3 is an enlargedsectional detail view of the clip of Fig. 8. Fig. 7 is a detail view ofthe spring 29 and connec tions thereof; Fig. 8 is a perspective view ofthe clip 18.

Referring particularly to the accompanying drawings, 10 represents thedraft poles or tongues of the cultivator, and 11 the beams of thecultivator frame. Mounted on the pole is a toothed segment 12, andpivotally mounted on this segment is a hand lever 13 provided with apawl 14 for engagement with the teeth 15 of the segment. This lever hasa rearwardly extending arm 16 to which is pivotally connected adepending link or rod 17.

Secured to the beams 11 by means of the Specification of Letters-Patent.

Serial No. 825,666.

clips 18 is an oscillating shaft 19 which is disposed transversely ofthe cultivator, and.

between the forward ends'of the gangs of shovels 20. tendingrearwardlytherefrom are the'frame bars :21, andsecured to these bars are thetransversely arranged angle bars 2-2. These angle bars 22 are furthersecured together by the bars Carried by each of the angle bars 22 arethe rearwardly extending curved rake teeth 2%, the teeth of one barbeing arranged in staggered relation to the teeth of the other bar. Thebar 23 extends to a suitable distance beyond the rear angle bar 22, andis provided with a vertical opening 25 through which passes the lowerend of the beforementioned rod or link 17. A pin 26 is passed throughthe lower end of the link 17 below the bar 23. At a point approximatelymidway of the length of the link 17,21 pin 2-7 is passed therethrough,and on the link below this pin is a suitable washer plate 28. Encirclingthe rod or link between the washer plate and the bar 23 is a coiledspring 29. When the lever 13 is pulled rearwardly the link 17 will movedown and swing the weeder frame down into operative position. The spring29 will yieldably hold the weeder frame in ground engaging position, andshould the frame strike an obstruction such as a stone, the frame wouldreadily rise against the tension of the spring, but be immediatelyforced down thereby after the obstruction was passed. By swinging thelever forwardly, the arms 16 will pull up on the link 17 and raise theweeder frame out of engagement with the ground.

This weeder attachment is particularly adapted for use in connectionwith straddle row cultivatorsand is placed directly in front of andbetween the gangs of cultivator shovels so that the weeds can be clearedfrom between the rows in advance of the shovels, thus making it easierfor the shovels to loosen the soil at the sides of the plants. Thedevice is simple in construction, and comparatively light so that thedraft of the cultivator will not be materially increased,

nor is there any danger of the weeder digging up or otherwise injuringthe plants.

I do not limit my invention to the exact details of construction,combination and ar rangement of parts, as herewith illustrated PatentedDec. 7, 1915,. I

Secured to the shaft and ex-,

and described, but my invention may only be limited by. a reasonableinterpretation of the claims.

What is claimed is: 1. In a Weeder attachment for a cultivator, apivoted frame carried by the beams of the cultivator between the gangsof shovels, weeder teeth carried by the frame,

tachment downwardly into resilient engagement with the ground.

2. A Weeder attachment for a straddle row'cultivator' comprising a framedetach ably pivoted on the cultivator beams and disposed in advance ofand between the gangs of cultivator shovels, weeder teeth carried by theframe, a lever mounted on the cultivator, a link pivotally connected tothe lever and to the frame, and resilient means on the link for holdingthe said frame yieldably in engagement with the ground.

In testimony whereof, I afiix my signature,cin the presence of twoWitnesses.
